| Abstract: | This paper introduces the prevention and elimination of scale forming in the evaporator in which the ammonium sulfite pulping black liquor is concentrated.The research result shows that ultrasonic treatment has obvious effect on the prevention of the scale formation.Therefore,the capacity and heat transfer coefficient of the evaporator are improved.The main reason of the scale prevention is the space effect and the non-linear vibration of the ultrasonic which increase the inducing period of the scale formation,reduce the number of the crystal grains and prevent their growing,and strengthen the capability of removing the grains.The research provides the theoretical basis to the practical application. |
| Keywords: | ultrasonic black liquor evaporator scale prevention evaporation capacity heat transfer coefficient |
